2 Claims.

This invention relates to changeable exhibitors and has. for its primary object the provision of a device of this character which may be readily used for any one of a great number of purposes and by means of which predetermined portions of a web can be exposed for use as and when desired. I

A feature of the invention resides in the novel coordination of two surfaces of a web and the provision of means for utilizing both sides of the web upon which sides the portions to be ccordinated with each other are printed or otherwise suitably arranged.

A more specific feature of the invention is directed to the form and construction of a portable structure having positively acting means for transferring positive motion to any selected one of a plurality of web supporting reels, so that the web can be moved in any one of two directions at the option of the user.

A further object is directed to a novel form of housing in which is contained a movably'supported reel, the housing having means to enable a plurality of like portions of the web to be displayed as desired. b I

Our invention also comprehends other features of construction which, together with those above specified, are fully described hereinafter and specifically recited in the claims.

Our invention will be better understood by reference to the accompanying drawings, in which Figure l is a perspective view of the device;

Figure 2 is a view in top plan'of the device showing a portion of the cover broken away to better disclose certain parts of the interior mechanism;

Figure 3 is a top plan view of a portion of the device showing the driving and driven means for the web reels;

Figure 4 is a vertical section through the device;

Figure 5 is a transverse section taken on line 55 of Figure 4; and

Figure 6 is a perspective view of a portion of a modified form of web.

It is to be clearly borne in mind that we propose to utilize both sides of a movably supported web for containing matter to be exhibited from a housing. We are not particularly interested in the specific use to which the device can be put, and, therefore, will claim broadly as our invention a means or mechanism in which both sides of the web can be used as just stated and one part of the web co-ordinated with a like part or portion of the same dimensions, and both said parts exhibited at one and the same time. Neither are we concerned broadly' with the means employed for moving the web, as this may be modified. within the scope of theclaims to meet particular conditions or uses.

In carrying the invention into practice, use is made of a housing consisting of the body forming parts I!) and II and a removable cover l2, the latter having apertures |3-l3 which are covered by a transparent panel I4. The part i0 is formed with spaced apart side walls l5l 5.

The part H-is formed with spaced apart side walls Iii-I6 and a connecting bottom H, the walls l5-l5, Iii-46 and said bottom I1 com-- bining to produce a housing of substantially rectangular form as shown in Figure 1, and as illustrated in Figures 2 and 4, the walls l5 are formed with vertical end flanges l8 against the inner surfaces'of which the ends of thewalls [6 are adapted to engage. The part I l is remov able from the part I!) in order that the part 10 can be entirely exposed when desired. I

The housing part I0 is provided with tables l9l9, which are disposed in the same hori zontal plane with each other and a third and somewhat similar table 20, the latter located directly beneath one of the tables [9 as clearly shown in Figure 4. Each of these tables is provided with end' flanges 2| having slots 22 for the reception of supporting studs 23 on the inner faces of the walls I5-l5. The alined tables l9l9 are disposed in parallel relation to the panel I 4 of the cover l2, there being sufiicient clearance between the upper surfaces of said tables and the under surface of said panel to enable a web 24 to freely move over the tables as will be fully appreciated on reference to Figure 4-. It willbe' further noted that the tables are disposed directly beneath the respective apertures l3 and that each table is approximately the same in size as the aperture with which it co-acts.

Mounted to rotate in the housing part II] and between the walls l5l5 thereof are reels 25 and 25a, the axis of rotation of one of which is parallel to the axis of rotation of the other. The web 24 co-acts with these reels, so that it can be unwound from one reel and wound onto the other. From the reel 2511, the web passes over the idle rolls 2626 on the right hand table I9 so as to provide a horizontal stretch A of a size to fill the overlying aperture l3, thence under the rolls 21-21 on the table 20, to provide a stretch B of the same area as stretch A, thence over the rolls 28-28 on the upper left hand table 19 to provide a stretch C of the same area as stretch A and of the same size as the overlying aperture l3, thence downwardly at D and onto the reel 25. Because of this manner of leading the web from one reel to the other, it follows that at one of the apertures l3, one side of the web will be exposed so as to be clearly visible through the panel A. and that from the other aperture IS the opposite side of the web will be clearly visible through said panel.

The reels 25 and 25a are each provided with an axle 29 whose opposite ends are journaled in the walls l5l5 and extending about the axle of the reel 25 and interposed between one side of the reel and an adjacent wall it: is a coil spring 30 to offer slight frictional resistance to rotation of the reel, as will be understood. The axle of the reel 25 has fixed thereto a gear pinion 3|. A similar pinion 32 is fixed to the axle of the reel 25a. A driving gear 33 is mounted to slide and turn in a bearing 34 on the adjacent wall l5 and when adjusted to the position shown in Figure 3, power can be positively delivered to the reel 25 upon turning the gear 33 counterclockwise. The gears' 3| and 32 are relatively offset from each other so that only one thereof can be intermeshed with gear 33 at a time. When the gear 33 is moved to intermesh with gear 32, power can be positively delivered to the reel 25a, also upon turning the gear 33 in a counterclockwise direction. When gears 3| and 33 are intermeshed and the gear 33 turned counterclockwise, the stretch A will travel in the direction of arrow e, Figure 2, and stretch C in the direction of arrow I. When, however, the gears 32 and 33 are intermeshed and the latter turned counterclockwise, the movements of the stretches will be reversed.

The construction and arrangements of parts herein provided will allow for complete utilization of both sides of the web, and matter can be printed on said opposite sides so that whatever matter is displayed at one aperture l3 will be coordinated with matter displayed at the other aperture. As an illustration of one use to which the device can be put, maps can be printed upon one side of the web and arranged in longitudinal series formation, while text matter can be arranged upon the opposite side and a proper portion of the text correlated with a particular one of said maps. Or the device can be connected in any suitable well known manner witha calendar clock so that at one aperture l3 the day of the month can be made to appear, while at the other aperture any text matter which is significant of a particular time can be printed, so that respective parts of the web can be co-ordinated with each other.

The device can be used as a retainer for newspaper clippings or the like, and as a means to enable same to be turned to a display position as desired. To enable the device to be so used, it is proposed that the web shown in Figure 6 be employed. This web has struck therefrom tabs 34 which may be pasted or otherwise suitably secured to the clipping 35, as illustrated. The webs herein disclosed may be constructed of paper or flexible material such as cloth or the like.

The shaft 36 which supports the gear 33 projects outside of the housing of the device and is provided with a knurled knob 31, whereby the gear can be manually operated.

What is claimed is:

1. A machine of the class described comprising a casing having a pair of windows in juxtaposition to each other, a pair of winding and unwinding reels, respectively, a web co-operable with both reels and adapted to be paid off of one and paid onto the other thereof, means for training the web over a course to expose one side of the web at one window and the opposite side of the web at the other window and comprising an uneven number of identical tables supported within the casing to dispose two thereof in the same horizontal plane with each other and beneath the respective windows and another thereof laterally opposite and in spaced parallel relation to one of the two just referred to, and each of said tables having parallel disposed end rollers over which the web can freely move and be correlated to the winding and unwinding reels to be paid off one thereof onto the other as aforestated, and means for operating the reels to enable the web to be moved as aforementioned.

2. In a device of the class described, a pair of rotary reels; driven means on each reel; driving means supported to enable same to be engaged with the driven means on any one of the reels; a web co-operable with the reels to be wound from one to the other thereof; means constituting a housing in which the reels and the respective driving and driven means are contained; and means within the housing for positioning one side of one portion of the web in a plane with the opposite side of a like portion of said web, the housing having windows from which said respective sides of the web can be displayed and comprising an uneven number of identical fiat tables in which two thereof are disposed in the same horizontal plane with each other beneath the respective windows and another one thereof laterally opposite one of the two aforementioned, and each of said tables having parallel disposed end rollers over which the web can freely move and be correlated to the aforementioned reels.
